Technology Connections Between Groups • Potential or existing areas for collaboration between groups: • Pulsed magnets and kickers • Low impedance strip-line kickers • Broadband requirements, high voltage reliability • Ongoing collaboration: DAFNE, Damping Rings groups • Fast rise- and fall-time high voltage pulsers with good amplitude stability and high reliability • Ongoing collaboration: DAFNE, Damping Rings groups • Methods to minimize kicker-induced orbit errors • Pulsed magnet design for on-axis injection schemes • Magnet Designs • High Field Wigglers and Undulators • Aperture, peak field, field quality and shimming, and non-linear optimization for widely varying applications • SC wire choices, properties, and methods for SC designs • Connection with vacuum chamber design: photon absorbers, electron cloud build-up, cold-mass heat loads, protection against losses, radiation damage • Conventional magnet approaches for low emittance cell design, particularly when “high occupancy” cells are required Low Emittance Rings 2010 - CERN
Technology Connections Between Groups • Alignment • Precision alignment and magnet fiducialization • Vibrating wire technique (with detailed study/suppression of systematic effects) provides alignment capability which is well-matched to low emittance ring requirements. • Beam-based alignment techniques • Real-time alignment technologies • Girder alignment/movers a magnet movers a correctors • Instrumentation • BPM Systems • Turn-by-turn capabilities and correction methods • Orbit feedbacks and maximum attainable bandwidths • Calibration and stability/repeatability issues • Synchrotron Radiation Monitors for Emittance Characterization and Tuning Low Emittance Rings 2010 - CERN
Technology Connections Between Groups • Feedback Systems • Impact of digitization resolution on low emittance operation • Specifications for control of instabilities in high intensity, low emittance rings • RF Systems • Low Level RF Design • RF Power – solid state amplifiers vs klystrons • Cavity design for various bunch structure requirements Low Emittance Rings 2010 - CERN
